SU380347A1 - CLASSIFIED CRUSHER - Google Patents

Description

one

The invention relates to the petrochemical industry, in particular to a classification crusher, primarily intended for large-scale crushing and simultaneous fractionation of petroleum coke, can also be applied in other areas of technology, for example in the coal industry.

Known classification crusher, containing split housing with receiving and unloading chambers, inclined drive rotor and drum screen with sieve and detachable.

The purpose of the invention is to provide simultaneous size controlled crushing and classification of coke.

This goal is achieved by mounting radial-end beams with tangential teeth on the rotor shaft and an adjusting gear mechanism made in the form of a lock sleeve with teeth at the end and fixedly fixed to the rotor of the upper sleeve with stepped teeth at the end and with the possibility of axial moving together with the sieve attached to it and the screen of the screen, as well as the adjusting sleeve with the teeth on the end, installed between the upper and the empty sleeves.

FIG. Figure 1 shows schematically a classification crusher, a longitudinal section;

in fig. 2 - adjusting gear assembly in the position providing maximum size of the crushed fraction; in fig. 3 - adjusting gear unit, in the position of ensuring the minimum size of the crushed fraction; in fig. 4 is a view along arrow L of FIG. one.

The crusher consists of split upper / and lower 2 buildings with prisoners between

rotor 3. On the upper case there are

charging port 4 and discharge chamber d.

On the bottom case there is a cover 6 for

inspection and discharge chambers 7 and 5. Rotor

3 crushers consists of a shaft 9, built in it beat 10 with teeth 11, a lattice screen 12 and a drum sieve 13, an upper sleeve 14 connected fixedly with a drum sieve 13, an adjusting sleeve /.5 and a locking gear sleeve 16 fixed

motionless on the shaft 9.

Crusher works as follows. The crushing product enters the loading port 4, is crushed by ingrown bilami 10 having teeth, and then falls on the screen of screen 12 where the primary sieving takes place.

The coarse fraction, rolling down the sloping screen of screen 12, is unloaded through chamber 5. The iodine sieve product enters the internal cavity of the drum sieve 13, where

due to rotation of the rotor 3, secondary sieving of the product occurs. The larger fraction is discharged through chamber 7, and the smaller fraction through chamber 8.

Obtaining pieces of a product of the required size is carried out by means of an adjusting gear mechanism consisting of an upper gear sleeve 14, an adjusting gear sleeve / 5: and a lock gear sleeve 16.

The upper gear bushing 14 has the ability only axial movement of the shaft 9, the adjusting gear bushing / 5 has the possibility of axial and rotational movements, and the locking gear bushing 16 is fixed on the shaft 9.

When turning the gear sleeve 15 around the axis of the shaft 9 with its preliminary movement, the sleeve 14 due to the presence of stepped teeth at its end will move in steps along the axis of the shaft 9 together with the drum grinder 13 and the screen ratchet 12;

this will regulate the distance between the strikers Yu and the drum bar 12.

Subject invention

A classification crusher comprising a split housing with receiving and unloading chambers, an inclined driving rotor, a drum screen with a sieve and a sieve, characterized in that, in order to provide an adjustable crushing of the product by size, radial-end beams with tangential teeth are mounted on the rotor shaft and adjusting gear mechanism made

in the form of a locking sleeve with teeth on its end face fixedly mounted on the rotor shaft of the upper sleeve with stepped teeth on the end face and with the possibility of axial movement together with attached drum

sieve and screening screen, as well as an adjusting sleeve with teeth on the end, installed between the upper and stop sleeves.
